Created attachment 184750 [details] gdb backtrace Hello, I have a large PDF file (almost 300 MB) containing thousands of audio files. It opens fine with Evince, but with Okular, the software freezes, and I have to manually terminate it without being able to view the file. If I launch it from the terminal, after a few seconds, I get these messages (and I don't have the courage to wait for it to finish...). By the way, « Trop de fichiers ouverts » means "Too many files open". okular big_audio_file.pdf ! SyncTeX Error : could not open, error 2147416319 !
